UNITED STATES PATENT OFFIC MEAD BLAKE, OF COMPTON, QUEBEC, CANADA.

ROOFING-PAINT.

SPECIFICATION Iorming part of Letters Patent No. 286,255, dated October9, 1883. Application filed April 6,1883. (No specimens.)

To aZZ whom, it may concern:

Be it known that I, MEAD BLAKE, a citizen of Canada, residing at town ofCompton, in the county of Compton and Province of Quebec, Canada, haveinvented certain new and useful Improvements in Roofing -Paints; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to water-proof and fireproof paints for tin,shingle, and other roofs, the object of which is to provide apaint thatwill neither crack by reason of cold nor run or become soft because ofheat.

To these ends my improved paint consists of the following-namedingredients, in sub stantially theproportions mentioned: coal-tar, fiftygallons; archangel tar, eight gallons; coaltar pitch, three gallons; rawlinseed-oil; five gallons; finely-ground rock salt, three gallons;asphaltum, three gallons; muriatic acid, fifteen pounds; hydrauliccement, seventyfive pounds. These ingredients are to be thoroughly mixedby agitation, and the compound applied to the roof in a boilingcondition.

When my improved paint is applied to a shingle or other wooden roofwhile in a heated state, the wood is thoroughly saturated at 0 thesurface, the pores filled, and a thick slightly elastic coating formedthat is not injuriously affected by heat or cold, and which renders theroof water and fire proof.

If desired, powdered emery may be used in lieu of hydraulic cement.

At times the commercial coal-tar is apt to be thinner than ordinarily,and when the coaltar is used in that condition in the preparation of mypaint the quantity of coal-tarpitcli should be slightly increased tocompensate for the difference in body of the coal-tar.

Having thus described my invention, What I claim,and desire to secure byLetters Patent of the United States, is-

The herein-described roofing-paint, consisting of coal-tar, archangeltar, coal-tar pitch, raw linseed-oil, finely-ground rook salt,asphaltum, muriatic acid, and hydraulic cement, substantially in theproportions specified.

In testimony whereof I affiX my signature in presence of two Witnesses.

MEAD BLAKE.
